VARIETY WOO D-WORKER.

SPECIFICATION forming part of Letters Patent No. 448,320, dated March 17, 1891.

Application tiled February l5, 1889. Serial No. 300,073. (No model.)

To all whom it may concern:

Be it known that I, HENRY J. CoLBUEN, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Variety food-Workers, and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that class of machines for wood-forming which are termed variety wood-workers,7 in which a rotary arbor journaled in proper bearing-boxes (one of which boxes is removable from the said arbor in a direction at right angles from the axial line of said arbor for the purpose of effecting and expediting an exchange of cutterheads) and properly combined with a pair of horizontally and vertically adjustable tables and with other parts and mechanism hereinafter explained is adapted to execute different forms and varieties of cuts.

Referring to the drawings, Figure lis a vertical side elevation of the entire machine; Fig. 2, a plan with a portion of the top of the table broken through. Fig. 3 is a vertical section on line A, Fig. 1. Fig. a is a vertical section on line I3 of the slide C and table D. Fig. 5 is a top view of the slide-connecting screw-shaft, showing the screw-nuts in section. Fig. 6 is an enlarged longitudinal sectional view of the cutter-head arbor and its supports, showing a cutter-head in posit-ion in full lines and in side elevation. Figs. 7 and S are enlarged views of the mechanism shown in Fig. 6, taken on line E ofA said gure and showing the removable box in its open and closed positions, respectively. Figs. 9 and 10 are enlarged front elevations of the guidefence, showing said fence in different vertical positions. Figs,11 and 12 are vertical end elevations of the guide-fence on line F, Fig. 9, Fig. 11 showing the said fence in a vortical, and Fig. 12 showing the said fence in an oblique, position. Figs. 13 and let are vertical sections of said fence on line G, Fig. 10, looking in the direction of the arrow Gf. Fig 15 is a plan of the base-plate of the guide-fence, also shown at I-I in Figs. 11 and 12. Fig. 16 is a Yside View of the connecting-link, also shown at I in Figs. 1l andlQ. Fig. 17 is a Vertical section on line 1, Fig. l, showing the screw K, nut L, and wheel S.

Similar letters refer to similar parts throughout t-he several views.

On either side of the cutter-head and resting on the main frame .I is located a two-part composite mechanism, whichI have termed a slide and a table. In each case the parts of this composite mechanism are unadjustably connected horizontally and adjustably connected vertically by self-contained means described belo w. The object of this construction is to render the superimposed table more rigid and better adapted to be adjusted to the varying sizes of cutter-heads than was accomplished in the old forms of machines of this character. Attached to and sliding' longitudinally upon this frame and adjustable horizontally in suitable guides are the slides O, their ends being cylindrical in form and bored vertically to iit the exterior' surface of the screws K, in which the said screws K, by means of the nutsLbeing'turned thereon, are adapted to be vertically adj usted in pairs by means of the connecting-chain M.

In Fig. 17 is shown in vertical section the screw K, its nut L, and wheel-connection S. Through a slot N, by means of a screw attached to the wheel O, the said slide C is secured to the frame J. At P in either of the slides O is a horizontal toothed rack having a corresponding' toothed pinion-wheel Q engaging it and a dapted to be operated by means of the wheel R. To show this rack P a portion of one of the slides C is broken away in Fig. l. At T is a shaft which is journaled in boxes at T', attached to the side of the frame J in any convenient position along its length, as shown in Figs. 1 and 5.

U U are holders attached to the tables D D', and each is of suitable size to receive the nut U', on which it loosely slides and to which it is adapted to be fastened by means of a thumb-screw V. The said nut U is threaded to correspond with the thread adjacent to it upon the screw-shaft T. At either end of the shaft T is a hand-wheel T adapted to rotate in either direction the shaft T.

At NV is an axially-divided box pivoted atX and adapted to be opened and closed inthe direction of the dotted line YV. This pivot is IOO preferably attached to one end of the transverse slide Y, which slide is adj ustably secured to the `main frame J and moves transversely thereon in guides Y. At Z is a second box, and at Z a third box, also attached to the slide Y, and both of which are preferably ordinary journal-boxes. In these several boxesis journaled the cutter-head arbor 14. To the arbor the cutter-heads are secured, as shown in Fig. 6, by means of a screw-nut 3, which presses the said head longitudinally against the collar 4 in a Well-known manner. Locking-,arms 5 are pivoted at G at a right angle to the pivotal point X. of the divided box W, and a screw-bolt 7, attached to thel upper extremity of the said locking-arms 5, is adapted to close into the slot in the open lugs 8 upon the arms of the divided box W and to secure together and in position the said divided box W, as shown in Fig. 8.

At 9 a thumb-screw journaled in a lug y, attached to the slide Y and Working in a threaded nut 10, attached to the main frame J, is adapted to adjust thesiide Y and its attachments transversely to the length of said frame J.

At 11 and 12 are shown the two parts of a divided guide-fence,which are adj ustably pivoted together by means of a connecting-link shown-in dotted lines at 13 in Figs. 9 and 10 and Vin section at 13 in Figs. 13 and 14. This fence .is secured to one or both of the tables D and D., but preferably to the rear table D, in such a manner Well known that its angle of .inclination tothe surface of said vtables may bevaried, as shown in Figs. 11 and 12. I make no claim in this connection to any specific device for so varying the inclination of said table or for securing the said rest to said tables. Iuse for this purpose a device shown in Figs. 11, 12, 15, and 16, which was in substance patented to me December 6,1881, in Letters Patent Aof the United States No. 250,425. i

rllhe variety wood-Worker being a machine which is lin `common use and its adaptability and management Well understood, it will only be necessary to explain the operation of my and independently, the screw attached to the Wheel O is turned to loosen the slide C upon the fra-me J, when by means of the Wheel R the pinion Q is turned in the rack P and results in the horizontal longitudinal movement of the said table. IVhen it is desired to adjust vboth of the said tables D and D simultaneously horizontally toward or from each other,itis only necessary to tighten the thumbscrews V upon the nuts U, thus securing them in a iixed position in their holders U, when by means of the Wheel T the screwshaft T-is turned and results in the said yadjustment of the said tables, it being understood, of course, that vthe threads upon `the different `halves of the shaft T are set in opposite directions of pitch, as shown in Fig. 5.

To adjust either of the tables D or D vertically it is vonly necessary lto rotate the Wheel S in the vproper direction, which rotation Will actuate the nut L upon the screW K and in turn actuate the sprocket wheel L', upon which is the chain M, by which the nuts L upon opposite ends of the slide C are connected, and a corresponding movement will thus be imparted to the sprocket-Wheel L and both ends of the said table consequently adjusted simultaneously. By means of the thumb-screw 9 the transverse adjustment of the slideY is effected and theconsequent corresponding movement of arbor 14 in an obvious manner.

As before stated and explained, the tables D and D are adapted to be vertically vadj usted, and they carry the divided guidefence, consisting of the parts l1 and 12, and since the said parts 11 and 12 are loosely and adj nstably pivoted togetherit is obvious that when either of the said tables is vertically moved the part -of said guide-fence resting thereon will lpartake of its movement.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is
